Credit card switch still not done

I was approved for a credit card and I accepted the card on the reasoning that FNB would be able to settle my Credit card at nedbank and I would pay FNB back at a better rate of 9.9% for the first 9 months. This was approved and I received the card on the 21st of April. Till today the balance transfer has not occurred. I have repeatedly called the call centre and have been moved from pillar to post. To the point that the Team leader at the call centre decided to tell me that\ I need to calm down and allow his to do his job."the consultant Rudi Pillay at the westville branch has repeatedly tried to assist me with getting this done but to no avail from internally. I have sent through the settlement amount to FNB twice but still no settlement. Now nedbank is charging me interest for non payment which sill negatively impact my credit score. This is not the service I expected from a platinum card division. FNB is going against the service that originally gave me reason to move from Nedbank to FNB. """
